Ask HN: AWS Primer for Solution Architects

After spending the last couple of years working with Azure it sounds like I'll be going back to working with AWS. Azure has some great learning features on Microsoft Learn, where you can basically go through a course for any feature that they offer certifications in. This includes an online sandbox where you can create your own cloud components. From a quick look at AWS website I can't see anything quite as comprehensive. Would appreciate some suggestions on matching Azure components to AWS initially and also any sources e.g. Youtube channels that provide a good high level overview of services from a developer perspective.
